The current robotic crawler technology is an improved version of the technology from the 1980s, which had resulted in widespread premature leaks in the pipelines. The improve ments in the process and methodology of robotic crawler systems in coating girth weld interiors have tremendously decreased the leaks and severe corrosion previously found in water injection pipelines. With proper equipment on the improved robotic crawler, coupled with proper welding procedure, premature pipeline leaks can be avoided because the coatings can be applied holiday free. The improved system has restored confidence to pipeline owners, so much so that the robotic crawler system is now also used on pipelines construct ed offshore. It should be noted that other benefits come from the improved robotic crawler technology in other ways. Because of the considerable reduction in premature pipeline leaks, the current systems can help provide pipeline owners with savings in labor and money. Futhermore, the improved robotic crawler can be used to apply liquid coatings as well as FBE. Different generic coating types can be applied by changing the coating application machine and the attach ments that go with it. And pipeline construction time has been reduced through more efficient use of robotics and remote control mechanisms.
